Pressure and hardness tester of planar test piece

Discloses is a pressure and hardness tester of a planar material, comprising a base, a stage, a test frame and a test device. The test piece is flatly extended and fixed on the stage. The test frame comprises a floor stand and a cross bar hinged by a rotating shaft. The floor stand and the stage are fixedly connected with the base. One end of the cross bar is provided with a balance weight and the other end of the cross bar is provided with a counterweight and a connecting part. The connecting part is used to connect the test device including a pressure test assembly or a hardness test assembly and make the test device right opposite to the stage. After the cross bar rotates about the rotating shaft, the test device contacts with the test piece for testing a pressure resistance or a hardness of the test piece.
